Packaging structure and method for flexible liquid crystal display panels

Abstract

The invention discloses a packaging structure for flexible liquid crystal display panels. The packaging structure comprises a first substrate, a second substrate, a box sealing adhesive, a first polarizer, a second polarizer and a sealant, wherein the box sealing adhesive is located between the first substrate and the second substrate and is used for adhering the first substrate and the second substrate; the first polarizer is arranged on the outer surface of the first substrate; the second polarizer is arranged on the outer surface of the second substrate; the sealant is located between the first substrate and the second substrate and located at the outer side of the box sealing adhesive; and both the first polarizer and the second polarizer are polarizers with low water vapor permeability. According to the packaging structure, barrier membranes conventionally arranged on polarizers are saved, and the barrier membranes are integrated in the polarizers to obtain polarizers with low water vapor permeability; and meanwhile, a sealing wax layer is arranged at the outer side of the box sealing adhesive, and the polarizers with low water vapor permeability can effectively block the water vapor through being flush with two sides of the substrates, so that the performance and yield of the packaging structure are improved and the manufacturing cost is saved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a packaging structure and a packaging method of a flexible liquid crystal display panel. Background technique [0002] A flexible display panel, also known as a rollable display, is a display device that can be bent and deformed by making a visible flexible panel with flexible materials. Flexible display panels are one of the hottest trends in display technology. Although it has not been popularized in the market yet, it is foreseeable that scroll-type PDAs or e-book readers are no longer far away, and large-format wall-mounted flexible display panels will soon become a reality. For example, all visual materials, including various books, newspapers, magazines and video files, can be presented through this display and can be viewed anytime and anywhere. Flexible electronic displays have incomparable advantages. Like newspapers, they can be unfolded when needed, and rolled or ev...

Problems solved by technology

The inventors found that there are at least the following problems in the prior art: (1) In the existing packaging structure, at least one side of the first barrier film and the second barrier film should protrude from the edge of the first substrate and the second substrate by at least 0.5mm , so as to ensure that the sealant can be applied around, so the cost is wasteful; (2) the existing packaging structure needs to apply sealant between the two barrier films, because the gap is small, it is difficult to apply sealant, and it is easy to appear that the seal is not in place The phenomenon that water vapor in the environment can easily enter the interior of the LCD panel, resulting in abnormal display and other problems, affecting the performance of the LCD display, so the yield rate is relatively low
